AI Develops 16 Novel Viruses by Analyzing DNA Patterns

WHO:

Yahoo - Researchers at Stanford University and the Arc Institute conducted the study.

WHAT:

Yahoo - The AI model proposed 700,000 new potential genomes, which were narrowed down to 285 for testing.

Yahoo - The AI-generated viruses were observed to be similar to the Phi X-174 virus, with some mutations in their arrangement.

Yahoo - An AI model created 16 new viruses that had never existed in nature.

Yahoo - Out of 285 AI-generated viral genomes tested, 16 successfully assembled into functioning viruses capable of infecting bacteria and reproducing.

Yahoo - The new viruses were observed attacking E. coli bacteria and reproducing.

Yahoo - The researchers generated three E. coli strains that had evolved resistance to natural Phi X-174 and exposed them to cocktails made from the AI-designed phages, which overcame resistance in all three strains.

WHERE:

Yahoo - The study was conducted at Stanford University and the Arc Institute.

WHEN:

Yahoo - The study was published in the journal Science.

WHY:

Yahoo - The researchers noted that the new viruses were completely harmless to humans and did not train the AI on data from organisms known to affect humans.

Yahoo - The researchers aimed to explore the potential of AI in designing new viruses to combat antibiotic resistance.

HOW:

Yahoo - The researchers trained the Evo AI model on the 11 genes and 5,386 nucleotides of the Phi X-174 virus and about 15,000 of its closest relatives.

Yahoo - Researchers trained a genomic AI model called Evo on over 9 trillion nucleotides spanning over 128,000 genetic sequences drawn from millions of organisms.

Yahoo - The AI model learned statistical patterns in how biological DNA is arranged, similar to how a language model learns word combinations.

Yahoo - The researchers synthesized potential organisms using the AI-generated instructions, focusing on the Phi X-174 virus and its relatives.

Researchers have proposed an impressive 700,000 new potential genomes using an AI model, narrowing that down to 285 for testing. The AI-generated viruses showed similarities to the Phi X-174 virus, albeit with some mutations, and importantly, these new viruses were found to be completely harmless to humans. To achieve this, the researchers trained the Evo AI model on the genes and nucleotides of the Phi X-174 virus and its closest relatives.

Researchers at Stanford University and the Arc Institute have developed an AI model that created 16 new viruses never before seen in nature, successfully assembling them from 285 AI-generated viral genomes. These new viruses were observed attacking E. coli bacteria and reproducing, even overcoming resistance in strains that had evolved against natural Phi X-174. The study, published in the journal Science, aimed to explore how AI can be harnessed to design new viruses as a strategy to combat antibiotic resistance.
